Yeah, there is quite a bit of bitching going on on their forums. For me it is really messed up, graphical glitches, including textures looking like "white noise", lag even when not in online mode and random crashes. I hope they can sort it out.
edit: also, the few times I got it to run properly, they really seem to have dropped the ball on their quality control. Compare for example the Israeli weapons with the new AK models from the patch before this one. Then there is stuff like the players hand glitching through the MG3s magazine. Of course all very cosmetic stuff, but still, you expect more from PR after the other patches.
